And in premarket trading on Wednesday, shares were down by as
much as 8%.

Chipotle posted earnings per share of $4.59 and revenues of
$1.22 billion. Same-store sales — at locations open for at least
one year — grew 2.6%, beating expectations.

Analysts had estimated that Chipotle earned $4.62 in
adjusted earnings per share on revenues of $1.22 billion. They
had forecast that same-store sales rose 2.5% during the quarter,
according to Bloomberg.

Chipotle's restaurant-level operating margin fell 50 basis
points from third-quarter 2014 to 28.3% due to higher labor
costs. The company opened 53 new restaurants in the quarter.

The company said it expects low-to-mid single-digit same-store
sales growth for 2015, and between 215 to 225 new restaurant
openings, up from the previous forecast for 190 to 205.

The stock rocketed about 12% in the month following the
second-quarter results this year, when Chipotle smashed
earnings expectations.

The company had supply-chain
issues this year, and stopped serving pork at hundreds
of restaurants because some suppliers violated its standards.

Co-CEO Steve Ells said in the
statement: "As we have grown our restaurants through the
year, we are able to push our standards higher in what we can
accomplish with our food culture. We have currently returned
carnitas to 90% of our restaurants, and will look to bring it
back to 100% of restaurants during the fourth quarter."

Chipotle shares are up 3% year-to-date and 8% over the last 12
months.Google
